电动汽车续航里程的研究分析与优化

Research Analysis and Optimization of Electric Vehicle Range

目前,电动汽车的续航里程受众多因素影响。文章首先分析了会对续航里程产生影响的外部因素以及具体的影响原因,然后建立相关的数学理论公式。通过Matlab来仿真得出曲线图进行分析,分析得出,影响续航里程的因素主要是迎风面积、系统效率、车身重量、滚动阻力、电池容量、空气阻力,根据以上因素所得出的结果进行优化分析,以期望最大化的优化电动汽车的续航里程,并提供可行性建议。

At present, the range of electric vehicles is affected by many factors. Firstly, this paper analyzes which external factors will affect the range and the specific reasons, and then establishes the relevant mathematical theoretical formula. Through the simulation of Matlab, the curve is obtained for analysis. It is concluded that the main factors affecting the range are windward area, system efficiency, body weight, rolling resistance, battery capacity and air resistance. According to the results of the above factors, the optimization analysis is carried out to maximize the range of electric vehicles, and provide feasible suggestions.
